Abstract
The invention relates to a device (1) at a collapsible core (2) for a plastic- injection-moulding machine (3) for plastic and where the core (2) has a plurality of segments (4, 5) that in an interconnected state (I) form an inner core (2) of the mould (6), and that an axially movable (8) central pin (9) is received centrally (7) in the core (2). According to the invention, the segments (4, 5) are separated from each other as well as from the central pin (9) and are securingly received pivot ably mounted in a movable ejector pin plate (22).
